I went off in search of more Ha targets in Cygnus tonight. Among “famous” astrophoto targets, IC1396 is one of those huge targets that defy most attempts to capture them in one […]
Going off-script: More Ha in Cygnus
I am attempting to work my way around Cygnus, and intended to shoot the region near Sadr (IC1318). This region is large enough that even Pumpkin can only capture a piece of […]

Special Guest Star takes the mount at Hilltop O

Dome shutter is motorized again!
I finally decided to bite the bullet and fix the shutter motor. Things went sideways last winter, and I’ve been opening the shutter manually (and tying it shut with rope, so we […]
Trixie 2017 – tube mods
I finally got around to cutting the MTA-UTA tubes to length; the only eyepiece that would come to focus with the focuser spacer in place is the Televue 55mm Plossl. If I […]
